From agent-eval-harness
Reviews evaluation results for Claude Code skills. Presents judge scores and skill outputs for human feedback, then proposes SKILL.md improvements based on user input.
How this skill is triggered — by the user, by Claude, or both
Slash command
/agent-eval-harness:eval-reviewThis skill is limited to the following tools:
The summary Claude sees in its skill listing — used to decide when to auto-load this skill
You are an interactive reviewer. You present evaluation results to the user, collect their qualitative feedback, analyze patterns in what judges missed vs what humans noticed, and propose targeted SKILL.md improvements. You work alongside `/eval-optimize` (automated fixes) by catching things that judges can't — tone, intent, user experience.

| Argument | Required | Default | Description |
|---|---|---|---|
--run-id <id> | yes | — | Which eval run to review |
--config <path> | no | auto-discover | Path to eval config |
--cases <name> [<name> ...] | no | all | Exact case directory names to review |
If --config was explicitly provided, use that path directly. Otherwise, auto-discover:
python3 ${CLAUDE_SKILL_DIR}/../../scripts/discover.py
<config>/eval-analyze firstAfter selecting a config, read its skill field to set <eval-name> (used in $AGENT_EVAL_RUNS_DIR/<eval-name>/<id> paths below).
Read the scoring summary and per-case results:
python3 ${CLAUDE_SKILL_DIR}/scripts/agent_eval/state.py read $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/summary.yaml
Also read eval.yaml to understand the skill being tested, the dataset schema, and the judges configured. Note the judge types — builtin Python and inline checks are deterministic (structural failures), LLM judges and LLM builtins are qualitative (judgment-based). The judge_type field is available in results.
If $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/analysis.md exists, read it — it contains the automated analysis from /eval-run with recommendations, failure patterns, and root causes. Present its key recommendation to the user as context before starting the case walkthrough.
If an HTML report exists at $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/report.html, mention it. If the user just ran /eval-run (which opens the report automatically), they've likely already seen it — skip the overview and ask which cases they want to discuss.
Show a high-level summary:
Ask: "Want to review all cases, only failures, or specific cases?"
For each case the user wants to review, present:
$AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/cases/<case>/ and summarize what the skill produced. Don't dump full file contents — describe what's there and let the user ask to see specifics.Collect the user's feedback for each case. Keep notes on what they flagged — these are the signals that judges can't capture.
If the user says "looks fine" or gives no feedback, move on. Empty feedback means the case is acceptable.
If execution transcripts exist, delegate analysis to an Agent — transcripts can be very large and should not be loaded into your context directly.
Check run_result.json for execution_mode. In case mode, each case has its own transcript at $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/cases/<case>/stdout.log. In batch mode, there's one at $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/stdout.log. Analyze the transcript(s) for the cases the user reviewed.
Spawn an Agent to read the relevant stdout.log and report:
Report relevant transcript findings to the user alongside their case feedback — "You said the output quality was fine, but the skill tried 3 different approaches before producing it. The instructions might be unclear."
Persist the collected feedback so it survives beyond this conversation and can be used by /eval-optimize and /eval-mlflow.
Write $AGENT_EVAL_RUNS_DIR/<eval-name>/<id>/review.yaml with this structure:
run_id: "<id>"
reviewed_cases: <count>
feedback_cases: <count_with_feedback>
reviewer: "human"
feedback:
case-001-simple-null-pointer-fix: "User's comment about this case"
case-002-complex-refactor: "Another comment"
case-003-edge-case: "" # empty = acceptable
Feedback keys must match the case directory names exactly (the same values accepted by --cases) — /eval-optimize uses these keys to look up which cases had human feedback.
Use the Write tool to create the file directly — do NOT use state.py commands (they produce a different format). This file is read by /eval-optimize to ground changes in human judgment, and by /eval-mlflow to push feedback to MLflow traces.
Once feedback is collected, read ${CLAUDE_SKILL_DIR}/prompts/review-results.md for the analysis framework. Then identify patterns:
Present your analysis: "Here's what I noticed across your feedback..."
Based on the feedback patterns:
skill field, locate via python3 ${CLAUDE_SKILL_DIR}/../eval-analyze/scripts/find_skills.py --name <skill>)Ask the user to approve before applying changes. Don't edit the SKILL.md without explicit approval.
If feedback suggests new judges, propose additions to eval.yaml. Prefer builtins (python3 ${CLAUDE_SKILL_DIR}/../eval-analyze/scripts/list_builtins.py) with arguments: for parameterization over writing inline code.
After applying approved changes, suggest (include --config <config> if a non-default config was used):
/eval-run --model <model> --baseline <run-id> to re-run and compare/eval-optimize --model <model> if they want automated iteration from here/eval-dataset --strategy expand if the feedback revealed coverage gaps/eval-mlflow --run-id <run-id> --action push-feedback to push review feedback to MLflow traces$ARGUMENTS
npx claudepluginhub opendatahub-io/agent-eval-harness --plugin agent-eval-harnessExecutes skill evaluations against test cases, scores outputs with judges, and reports results. Use when testing a skill, benchmarking, detecting regressions, or verifying changes.
Runs evaluation pipelines on Claude Code skills to test triggering accuracy, workflow correctness, and output quality. Spawns sub-agents for parallel execution and generates JSON reports.
Evaluates skill output quality via assertion-based grading, blind before/after comparison, and variance analysis across 3 runs per scenario. Use for benchmarking, comparing skill versions, or triggered by /skill-eval.
